Product details
Overview
SMBG13-E3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 13 V standoff voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 21.5 V clamping voltage (VC) at 27.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMBG13-E3/5B datasheet, SMBG13-E3/5B pinout, SMBG13-E3/5B application, or SMBG13-E3/5B equivalent, key selection considerations include its unidirectional polarity, AEC-Q101 qualification, 150 °C maximum junction temperature, RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device in series with protected circuitry, conducting only when reverse voltage exceeds VBR to limit transients to ≤21.5 V. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1 ns), critical for safeguarding MOSFET gates and microcontroller I/O against ESD and inductive switching spikes.
Thermal performance is defined by RθJA = 100 °C/W (on recommended pad layout) and RθJL = 20 °C/W, enabling reliable operation up to 150 °C junction temperature. The device meets MSL Level 1 per J-STD-020 and passes JESD201 Class 1A whisker testing, confirming suitability for high-reliability automotive PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/5B | Same VWM/VC, but lower PPPM = 600 W (same rating), identical DO-214AA package - differs only in JEDEC prefix and minor thermal resistance | Identical functional use; validated in same AEC-Q101 test plan but different base part family | Select SMBJ13A-E3/5B if legacy design uses SMBJ footprint and requires cross-family sourcing flexibility |
| 1.5SMC13A | Higher VC = 21.5 V (same), but larger DO-214AB (SMC) package - 1.5× larger board area, RθJA = 30 °C/W vs. 100 °C/W | Better thermal handling for sustained surge duty, but incompatible with SMBG land pattern | Choose 1.5SMC13A only when board space allows and higher thermal margin is prioritized over miniaturization |
Compared with SMBJ13A-E3/5B, SMBG13-E3/5B offers identical electrical protection in a smaller DO-215AA footprint ideal for dense automotive layouts; versus 1.5SMC13A, it trades thermal derating headroom for space savings and automated placement compatibility.

FAQ
What is the clamping voltage of SMBG13-E3/5B at its rated peak pulse current?
The SMBG13-E3/5B has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPPM) of 27.9 A, measured using a 10/1000 µs waveform. This value ensures protected circuits remain within safe voltage margins during standardized surge events, and is confirmed in the Vishay datasheet Document Number 88456, page 2.
Is SMBG13-E3/5B suitable for automotive applications?
Yes, SMBG13-E3/5B is AEC-Q101 qualified and explicitly listed in Vishay's automotive-grade product documentation. Its construction - including glass-passivated junction, MSL Level 1 rating, JESD201 Class 1A whisker resistance, and -55 °C to +150 °C operating range - meets requirements for under-hood and body-control module deployments.
What does the "E3/5B" suffix indicate in SMBG13-E3/5B?
The "E3" denotes RoHS-compliant, commercial-grade construction with matte tin plating and JESD201 Class 1A whisker resistance. The "/5B" specifies packaging: 3200 units per 13-inch plastic tape-and-reel, per Vishay's ordering information table in Document Number 88456, page 3.
How does SMBG13-E3/5B differ from bi-directional variants like SMBG13CA?
SMBG13-E3/5B is unidirectional, with polarity marked by a cathode band and intended for DC line protection where reverse conduction must be blocked. In contrast, SMBG13CA is bi-directional, lacks polarity marking, and clamps symmetrically in both directions - making it suitable for AC signal lines or differential buses, not DC power rails.
What is the thermal resistance of SMBG13-E3/5B, and how does it affect layout?
SMBG13-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This requires adherence to Vishay's recommended pad layout to avoid thermal derating; reducing pad size increases junction temperature and reduces surge endurance.
